Pavement hydroplaning risk evaluation with Inertial Measurement Unit (IMU) and 1mm 3D texture data
(2015-07)
During wet weather automobiles traveling on pavements may experience hydroplaning that would cause out-of-control accidents. Annually 14% of all accidents with fatalities occur on wet pavements. However, not many studies ...
Novel system of pavement cracking detection algorithms using 1mm 3D surface data
(2015-12)
Pavement cracking is one of the major concerns for pavement design and management. There have been rapid developments of automated pavement cracking detection in recent years. However, none of them has been widely accepted ...
Feature investigation using micro computed tomography within materials
(2018-05)
This work uses micro computed tomography, as a direct non-destructive tool, to investigate the internal 3D microstructure of different materials at multiple length scales to provide insights that are of interest to the ...
Modeling heat transfer in mass concrete floors with radiant heat from ground source systems
(2017-05)
Thermal properties of concrete have been extensively studied for the design of mass concrete structures regarding cracking and stress development considerations. The rise in blended cement with limestone and fly ash as a ...
Evaluation of emissions reduction strategies for heavy duty diesel construction equipment
(2018-07)
Heavy-duty diesel (HDD) construction equipment expends a considerable amount of fuels and correspondingly emits a substantial amount of pollutants to the air. This dissertation assesses potential impacts of diesel exhaust ...
Pavement safety evaluation with 1mm 3D laser texture data
(2015-07)
Pavement safety is highly associated with surface texture characteristics. Measurements of surface texture can be conducted in either stationary or high-speed way. Texture data collected from the existing systems are ...
Exploring pavement texture and surface skid resistance using soft computing techniques
(2017-12)
Pavement skid resistance and texture characteristics are important aspects of road safety. Traditional pavement friction measurement from limited contact with pavement is influenced by multiple factors such as temperature, ...
Development of predictive modeling tools for estimating fuel use and emission rates for heavy-duty diesel construction equipment
(2014-05)
Heavy-duty diesel (HDD) construction equipment consumes a substantial amount of fuels and consequently emits a substantial amount of pollutants into the environment. This dissertation presents methodologies for estimating ...
Development of a productivity-based economic, energy, environmental model for heavy duty diesel construction equipment
(2013-05)
The use of heavy duty diesel (HDD) equipment in infrastructure projects accounts for a large quantity of fuel consumption, pollutants emissions and the majority of the total cost of the project compared to others. Construction ...
Evaluation of pavement skid resistance using computational intelligence
(2018-08)
Pavement micro-texture is affected by the aggregate characteristics contained within the surface. It is long desired to develop friction prediction models using pavement surface and aggregate textural properties. However, ...
